As the Washington Post reports, Maryland sought to recall Confederate-flag license plates in the 1990s, long before the debate over Confederate symbols was renewed by a recent mass shooting at a black church in Charleston, S.C. At the time, the state’s plan was frustrated by an injunction, after a federal judge ruled the plates a kind of speech protected by the First Amendment.

In the wake of a U.S. Supreme Court ruling which determined that license plates are in fact government speech, state Attorney General Brian Frosh put in a request to lift the injunction, which was fulfilled Thursday.
